Abstract
Provided on a chip are a plurality of conductor patterns for forming a coil, and a connection-relationship control device for controlling connection between adjacent conductor patterns. By switching the connection relationship of the conductor patterns by the connection-relationship control device, it is possible to form a coil of a desired shape at a desired position.
Claims14
An integrated circuit device comprising:
- plurality of substrates on which coils are formed, the plurality of substrates being stacked for performing signal transmission by electromagnetic coupling between opposing coils,
- the substrate including:
- a plurality of conductor patterns;
- and
- a connection control device that controls connection between end portions of said conductor patterns that are adjacent to each other;
- the coil being formed by connecting desired ones of the plurality of conductor patterns into a loop using the connection control device.
